The concept of evil poses great challenge to our thoughts. What is evil, where does it come from? After all, those who commit evil acts, are in fact, or at least look like ordinary people. Is evil part of human nature? Complex topic!
Here it is : establish and maintain absolute power, never admit a mistake or failure, lie consistently, spread disinformation, persecute those who disagree with you.
I must confess, I've never taken much interest in the evil characters of humanity (Hitler, Stalin, Mussolini, etc..). I spent no time reading books or watching movies featuring them. That much I know - Evil and its heroes have always been, and always will be, here and there, ready to strike.
I do take interest in the people though - those who could and did try to prevent evil. Not much has been done about prevention as people are engaged in the difficulties, pleasures, and intrigues of life which they claim to be short. Life is indeed short, and I'm not sure at all whether we, humans, can actually prevent evil and disaster.
Along the years, Man has violated God's World Creation, and judging by the climate change , wars, and various other existing conflicts, it doesn't seem certain He'll be willing to give us another chance in case of world destruction.
However, God might help with the survival of individuals and groups that are not ignoring His omnipresence and not using His name in vain, for getting power and money meant to harm the others.
